CASIO CZ-230S Electronic Synth 49 Keys Synthesizer

The CZ-230S was released in 1986. Despite the CZ-230Ss model numbering, it was not really a programmable synthesizer; the specifications of this model more closely resembled that of one of Casio’s home keyboard models. It used the synthesizer technology of the CZ-101 in a 100 tone preset sound bank, had a mini keyboard of 49 keys, incorporated the RZ1 drum computer technology and had a built-in speaker. Only four of the sounds in the sound bank could be programmed by linking the synthesizer to a computer via its MIDI port. 
In perfect working condition, comes with a power adaptor.
